Presented　in　this　report　is　a　new,　simple　and　effective　method　for　synthesizing　hierarchical　dumbbell　shaped　CeO2　derived　from　a　Ce-BTC　MOF　at　room　temperature.　The　product　was　characterized　using　Xray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　transmission　electron　microscopy　(TEM),　Fourier　transform　infrared　spectroscopy　(FTIR)　and　Raman　spectroscopic　measurements.　When　used　as　an　electrode　in　a　supercapacitor　with　a　KOH　electrolyte　and　a　K4Fe(CN)(6)　redox-active　additive,　the　capacitor　exhibited　large　a　specific　capacitance,　high　rate　capability　and　good　cycling　stability.　Capacitances　of　779　and　501　F　g(-1)　were　achieved　at　rates　of　1　and　15　A　g(-1).　Simultaneously,　the　capacity　retention　was　maintained　at　nearly　91%　after　10000　cycles.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
